Spin-Orbit Angles: Reflections of Dynamics in Systems

Abstract

We will present our campaign to estimate the projected spin-orbit angle for transiting hot Jupiters, measured by observing the Rossiter-McLaughlin effect. Combining our efforts to those of other teams we show what the current distribution in projected spin-orbit angle is. Following this we elaborate on how this compares to migratory theories in conjunction with other pieces of evidence.
